Rick, 68, and Lynn Bynes, 66, appeared somber as they attended the Friday hearing along with their attorney Tamar Arminak, who stated that the reason for the conservatorship application was because the parents feared their daughter would be released following her three-day hold.

"My clients only want the best for their daughter," Arminak tells PEOPLE. "They love her very much."

Reiser set a new hearing for Aug. 9, when he hopes Amanda would be present in court, facilitated by her court-appointed attorney, Mary Shea.

"I need to have a dialogue with [the actress] to gauge the propriety of a conservatorship to move forward," Reiser said. "There are issues of liberty and property."

It appears the actress's parents have limited access to their daughter in the hospital because Arminak told the judge the facility forbade them from giving formal notice to the actress of the conservatorship application.

Legal experts say that even though an adult is having a psychiatric episode, if the patient does not sign a consent to allow family members to get involved, a hospital by law must honor the patient's privacy.
